Greeting and salutations

The nine new witches went on with their lives they became modern people Amanda found a girl to date eventually gotten married Jazminka met a cute boy got together constanzes had also gotten married and pretty much everybody else except for Akko and Dianna they hadn't found love but they believe they have love for eachother (but they don't know it yet.)

So what happens when Diana is kidnapped? When she also starts to become more powerful by the minute?
Or when the person that kidnapped her, has trapped her in Hell?
